Stage 1 (pre-seed and seed)

Test with money before writing real code

A founder at S1 with an idea must decide whether to build now or validate first because most projects fail from building before thinking.

Options

Build immediately from the idea

Test a numeric hypothesis with cheap demo artifacts

Validate with surveys and interviews only

What mattered

What was done

ClaimValidate with a numeric hypothesis and real payment before building; a demo people like is not a business.
